The author of this book gives a brief history of Maria Montessori and how she discovered how children learn. It then goes on to describe the methods used, and gives detailed instructions for all the exercises and demonstrations which are used with preschool-aged children.

The author also gives instructions for making many of the Montessori materials at home, with common household items or easy-to-obtain craft supplies. Throughout the book she offers many alternative suggestions for the materials which are typically used in a Montessori classroom. For instance, she mentions that a muffin tin can be used very effectively to sort buttons, and that a handtowel may be used for the workmat.

Although this book was orginally written in the 1960's, most of the information is still useful today. The cover mentions that it has been updated and revised, but it is not clear what information has been changed in this edition. Still, overall this book is a wonderful resource for frugal parents who are able to teach their children at home, and who want to use Montessori methods to do so.
